General Background to this report

Using data from the LANDFIRE program we drafted these LTA-specific reports that depict:

  • How many acres of the most prevalent historical ecosystems (called “Biophysical Settings”, BpS) were present just prior to European colonization
  • How many acres of the most prevalent current ecosystems (called “Existing Vegetation Types”) were present ca2020
  • Past vs. current succession class amounts for 3 most prevalent BpSs

These charts provided as a demo only. Local review and interpretation will be key to success!

Reference vs. current succession classes for most prevalent Biophysical Settings

The following chart illustrates modeled “Reference” percentages compared to mapped current percentages of LANDFIRE Succession Classes for the top 3 Biophysical Settings in the LTA. The charts are illustrative only. To understand what the succession classes represent it is necessary to read the descriptions that are downloadable here.
